Iframe Usage in Forge Jira Custom UI’s

Iframe Usage in Forge Jira Custom UI’s,But it reminds me of the CSP problem, is there any solution for this?
error:Refused to frame ‘https://****.io/’ because it violates the following Content Security Policy directive: “default-src ‘self’”. Note that ‘frame-src’ was not explicitly set, so ‘default-src’ is used as a fallback.
I need to embed an iframe in the jira app.

Hi @Mockplus ,

Are you following the Custom UI guidance? Is any of this not working for you? The intention of Custom UI is that Forge hosts the app’s iframe - it’s not designed for iframes hosted externally.
